Actually, Lu Yu was really being modest.
It was because he often helped his mother rub the leaves of the Lychee Orchid when he was young. After rubbing it a lot, and with his mother's guidance, he was able to practice.
If an ordinary person were to directly touch it, they would only end up with a scratch.
Just think about it, if you put a pile of vegetable leaves in a basin and rub them with your hands, wouldn't they break in minutes?
It was the same logic.
After rubbing the indigo leaves, Lu Yu did not rush to start the next step. Instead, he stood up and waited for a while.
Lee Zhengxiao, who was holding a wooden stick and not knowing what to do, waited for a long time. He looked at the leaves in the stone mortar and said eagerly,
"Brother Lu, can you crush them now? I'm so free!"
"I still have to wait a little longer."
Lu Yu looked down at the indigo leaves in the stone mortar and said with a smile,
"This step is to wait for these leaves to 'wake up'. After they woke up, they would be processed to make the color even more beautiful and moving.”
Little Brother Lu Yu just said that he would wait for Ye Zi to wake up before proceeding to the next step. This excuse was so cute.
You're awake, you're going to die soon.
I suspect that there is a childhood trauma upstairs. Identification complete.
On one side, the netizens were having a heated discussion. On the other side, Professor Wang was nervously taking notes step by step according to Lu Yu's instructions.
After seeing the way Lu Yu rubbed the indigo leaves, he already believed that this young man really had some ability.
The steps that he was going through were very likely the true steps of the lost Aizen!
For example, Lu Yu had said that he had to wait for Ye 'zi to " wake up ", which was something he had never tried before!
If one were to analyze it from a scientific point of view, it was estimated that the internal structure of the leaves had been destroyed by rubbing. A certain amount of time had to be given for a certain substance in the leaves to fully react.
In this way, the color produced would be even more dazzling.
Professor Wang was really looking forward to what color Lu Yu could make.
After waiting for about 10 minutes, Lu Yu looked down at the color of the indigo leaves in the stone mortar.
Very good, it was almost at the appropriate level.
He raised his head and looked at Lee Zhengxiao, who was standing at the side with nothing to do. He said,
"Zhengxiao, it's your turn now. Remember to be gentle and not splash the juice.
After all, I've only collected a few stalks. If I splash them everywhere, I'm afraid it won't be enough.”
"Alright, I understand."
Lee Zhengxiao nodded, put the wooden rod into the stone mortar, and gently pounded it.
"Eh…"
Feeling the touch of the leaf under his hand, Lee Zhengxiao let out a soft sigh.
"This feels so soft. It's like pounding cotton. I don't need to use any strength at all!”
"That's right. Not only will the color of the indigo leaves look better after being fully kneaded, but it will also save more effort when pounding. The rate of juice seeping out will also be higher.”
Lu Yu explained with a smile.
While Lee Zhengxiao was busy, Lu Yu was not idle either.
He took out five or six porcelain bowls from the kitchen, each filled with spring water that had just been brought over.
Every time Lee Zhengxiao pounded for a while, Lu Yu would ask him to stop and observe the appearance of the indigo leaves in the stone mortar. Then, he would dip his finger into a drop of juice from the leaves and drip it into the bowl to observe the color.
After repeating this process for the fourth time, Lu Yu finally stopped.
"Alright, Zhengxiao, you can stop now.”
Professor Wang, who had been watching Lu Yu's actions in front of the computer screen, was shocked.
Of course, he understood that Lu Yu's actions were to "check on women."
According to the records in the ancient books, only craftsmen who were very familiar with the dyeing industry and were very sensitive to color differences could carry out the " color inspection."
Although the slight difference caused by the same plant being pounded at different times might not seem obvious at the time, the color difference formed after dyeing could be described as heaven and earth.
Therefore, in ancient times, every dyeing workshop would have a master craftsman who checked the color.
The higher the person's ability to check color, the better the quality of the dye workshop.
However, the conditions for checking color were too harsh. Even if one went to learn it specifically, without talent, it would be difficult to get a glimpse of it.
Therefore, in ancient times, it was hard to find a master craftsman who knew how to check color.
In modern technology, color checking could already be done by machines, but the time needed for the machine to check the color was too long. By the time the machine finished checking the color, the paint would have already been oxided.
Therefore, in the past few decades of research, even if Professor Wang knew about the technique of color detection, he had never really used it. Instead, he relied on his feelings to determine the color.
Although he could occasionally make good blue-dyed products, he could not guarantee that he could make them every time.
And now, this unknown streamer in the live broadcast room was actually using the method of checking the color of the water to determine the degree of kneading of the indigo leaf juice!
How could he not be shocked!
Professor Wang didn't think that Lu Yu was deliberately mystifying things. If one didn't specialize in blue dyeing, one wouldn't understand its power at all.
The people in the live broadcast room were also very curious when they saw Lu Yu dripping the juice of the leaves into the bowl drop by drop. They all sent bullet comments to ask for the reason.
Professor Wang saw this situation and was afraid that Lu Yu would delay his homework in order to answer their questions. He quickly typed on the keyboard and explained the technique that Lu Yu had just used in as common a language as possible.
As expected, another wave of commotion was stirred up.
I thought the streamer was just playing around. I didn't expect this to be a long-lost technique...
I'm ashamed for thinking that Lu Yu spent a long time in the water.
It seems that this is really a skill that requires a strong ability to distinguish colors. In my opinion, there is no difference between those bowls of water!
Lu Yu was busy with his work. He occasionally glanced at the live broadcast room and found that Professor Wang was sparing no effort to praise him. He found it a little funny.
It was indeed great to have someone help him with science, but there was no need to praise him like this.
It was as if Professor Wang was a troll army that he had hired. It was too much.
Seeing that Professor Wang had sent another bullet comment explaining how difficult it was to master the technique of checking color, Lu Yu couldn't help but ask,
"Professor Wang, it's really not difficult to check the color. Don't you know how to do it?”
Professor Wang's face froze.
The netizens in the live broadcast room could not help but laugh crazily.
This little bastard!
Professor Wang only felt hatred in his heart.
She was afraid of disturbing his work, so she specially helped him with the science. She didn't expect this little brat to not give her any face!
That's right! He just couldn't learn the simple technique he was talking about! What should he do then?
F * ck, the streamer is really interesting. I feel that Professor Wang might be in a difficult position now.
Was this the world of big shots?
I feel like I'm seeing myself in school. Brainiac: You don't even know how to solve such an easy question? Me: I don't know how to
I have a picture here, hahaha…
After a while, Professor Wang reluctantly sent a short bullet comment.
'I really don't know how to do it.'
The netizens in the live broadcast room started to laugh crazily again. However, this time, there were many bullet comments that said," I feel sorry for Professor Wang for a second."
Really?
Lu Yu was stunned and immediately felt a little embarrassed.
When his mother taught him when he was young, he really didn't think that this thing was difficult. He learned it after watching it a few times.
He hadn't talked to anyone about this ever since he grew up, so he had always thought that this was a skill that was easy to master.
Unexpectedly, Professor Wang really didn't know how to do it.
After thinking for a moment, Lu Yu said,
"Professor Wang, I'm sorry. I really didn't have any other thoughts just now. It was just a passing remark. It's mainly because my mother didn't spend much time teaching me when I was young, so I don't know much about this.
If you want to learn, I can teach you privately after the live broadcast. What do you think?”
Professor Wang's mouth twitched when he saw Lu Yu's sincere expression.
Of course, he was happy that Lu Yu was willing to teach him how to check on women. However, why did he feel like he deserved a beating when he said that...
After checking the color, the indigo leaves had been pounded into a very suitable state. Li Zhengxiao could not help with the rest of the work.
This was because the following steps required experience and touch.
Lu Yu walked to the stone table and picked up the two liang of plaster that Lee Zhengxiao had just helped to get from the old man in the tofu shop.
Lu Yu took out two pieces of the plaster and carefully held them in his hand. He slowly rubbed them in his palm.
Soon, the plaster fragments were ground into plaster powder.
Lu Yu picked up the chopsticks that he had placed at the side and slowly mixed the plaster powder into the indigo juice.
What was he doing?
Professor Wang was confused.
After checking the color, shouldn't it be time to boil the color water? It shouldn't be this step, right?
However, the professionalism that Lu Yu had shown previously made him stop posting questioning bullet comments.
Professor Wang's eyes widened as he watched Lu Yu's careful movements.
Could it be…Could it be that this kid even knew that technique?？
Professor Wang was unable to suppress the shock in his heart. Just as he was about to send a bullet comment to ask Lu Yu about it, he heard a very clear young girl's voice coming from outside Lu Yu's live broadcast screen.
"Brother Yu, can I come in?"
